Figure 86 shows the minimum-pin interface for applications using a standard SPI protocol.
The CS, SCLK, SDI, and SDO-0 pins constitute a standard SPI port of the host controller. The CONVST pin is tied to CS, and the RST pin is tied to DVDD. The SDO-1, SDO-2, and SDO-3 pins have no external connections. The following features are also available:
